Earthquake shock resistance system

ABSTRACT

Floating platform used as a base for any kind of structures to protect the structures from earthquake shock damages.

This application claims priority to provisional application No.60/599,820 filed on Aug. 9, 2004.

BRIEF SUMMARY OF MY INVENTION

This system works based on:

-   -   1—Archimedes' Principle.    -   2—Velocity changes in liquids with high density.    -   3—Unity of the shocking object.

The main point in this design is establishing a system that separatesthe direct connection between the structure and the earth. By using thissystem, the structure can be made in any way and from any materials,sizes and weight. This system concentrates on the base platform, as onesingle unit, for any construction. This platform is floated in ahigh-density liquid. Several cylinders filed with a gas, lighter thanair, are attached to the bottom of that base platform. These numerouscylinders are floating in a high-density liquid poured inside theconcave elastic bowl units.

DRAWINGS DESCRIPTIONS

FIG. 1:

Shows the top view of the whole design, giving the general introductionto the different part of this system. However the overall size and thequantity of the unit cells, (the concave elastic shells and thecontents), may vary base on the size and/or the weight of the structurewhich is supposed to be built over the “base platform”.

FIG. 2:

Presents the elevation of the whole system.

FIG. 3:

Presents the section view of the whole system and how it is puttogether. The reinforced concrete concave shell will be made same way asmaking a swimming pool. Then it filled with fine sands. The “elasticconcave shells” as shown t in the section view are placed and buriedinside the sands. The “elastic concave shells” are filled withhigh-density liquid. Metal cylinders filled with a gas lighter than airhave square metal top plate with four holes at four corners.

FIG. 4:

Shows the top view of one unit cell. The concave elastic shell, the highdensity liquid and the cylinder shows more clearly and closely.

FIG. 5:

Shows the elevation of one unit cell. The concave elastic shell, thehigh density liquid and the cylinder shows more clearly and closely

FIG. 6:

Shows the section view of one unit cell. The concave elastic shell, thehigh density liquid and the cylinder shows more clearly and closely.

FIG. 7:

It shows how the cylinders are screwed and attached to the bottom of thebase platform. Four screws attach the cylinders, through the four holesat four corner of the square top of the cylinder.

1- A structure, house, high-rise or bridge is builds over a baseplatform and attached to it The base platform is floated in a high-density liquid so that the earthquake shocks, vertical and/orhorizontal, could not hurt the structure. 2- A round concave shell,similar to a swimming pool construction, made of reinforced concrete isbuilt/placed over undisturbed earth. The dimension and the depth of thisshell will be relevant to the dimension and the weight of the structurethat is going to be built over the floating platform. 3- The concaveconcrete shell is filled with fine sands. 4- The numerous units ofconcave elastic bowls (same material as car tires) are placed in thesaid above sands in a way that the whole elastic bowl, except the last3″ top edge, is buried in the sands. This elastic shell bowl is filledwith a high-density liquid. Mixing different material can produce thehigh-density liquid. 5- One metal cylinder is floated inside eachelastic bowl. These metal cylinders are filled with a kind of gaslighter than air (can be determined by experiment). These cylinders areattached to the bottom of the base platform. This system works based onthe same principal as ships floating in the water. At the time ofearthquake shock, due to the high-density liquid, the sharp movement, inany direction, transformed to slow and soft motion, which eventuallytransfers this moves to the cylinders that are holding the base platformfloated. So the whole structure will moves back and forth and up anddown but with very smooth and slow motion. The elastic material works asextra shock absorber when the cylinders hit them. By using this system,the structure, which is attached and built over the base platform, willmove back and forth, up and down with slow motion.
